SPECIFICATION forming part of Letters Patent No. 718,341, dated January 13, 1903. Application filed June 5,1902. Serial No. 11013 46. (No model.)

To all whom it may concern:

Be it known that I, JOHN R. GRUNDY, acitizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Brushes, of which the following is a specification.

My invention consists of an improved form of brush particularly designed to be made of horsehair, bristles, or similar material, having for its object the provision of a brush of improved construction which shall have pro longed durability and usefulness.

A further object is to provide a construction such that when the hairs of the brush I5 are worn out or injured this part of the device as a whole may be replaced by a new one, the handle being used for an indefinite time.

These objects I attain as hereinafter set forth, reference being bad to the accompanying drawings, in which Figure 1 is a side elevation of the head or removable portion of one of my improved brushes, showing it as it appears before insertion within the handle of the brush; and

Fig. 2 is a side elevation, partly in section, of one of my improved brushes, showing the construction of handle whereby the head portion is maintained in position.

In the above drawings, A represents the handle of the preferred form of my improved brush, there being in the end of this a depression or cavity a, from the bottom of which extends into the handle a second cavity a of an elongated form and less in diameter than the first cavity. The head of the brush consists of two wires Z), twisted tightly together and holding between their strands bodies of horsehair B, although it will be understood that bristles or any other suitable material may be employed for this purpose. The hair tion 11 of the brush-head formed by the wires I) this is retained in position within the handle, so that it is practically impossible to remove it under ordinary conditions of use.

It is to be noted that my improved brush has no metallic portion exposed beyond the end of its wooden handle, and may for this reason beemployed around certain classes of .machinery in which brushes of the above-described form could not safely be employed. It will be seen that fused material within the cavity in the end of the handle is of such a nature as to firmly hold and maintain the twisted wires of the brush-head in position under all working conditions, and yet is of such a nature that after the bristles have become broken or worn out it is possible to remove the stub of the brush-head and replace it with a new head.

I claim as my invention The combination in a brush, of a handle, a head portion formed of twisted wires having brush forming material confined between them, said handle having within it a twopart cavity for the reception of said head portion,-one part of said cavity receiving the twisted wires and the second portion receiving and confining in position the brush-forming material held by said wires, and fusible material within the portion of the cavity for the twisted wires whereby the head portion is held to the handle, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN R. GRUNDY.
